Police filed a case against two teachers including a lady teacher of a private school here today, after a class Xth student who was allegedly punished by them developed fever and died after undergoing treatment, prompting protests by relatives of the deceased.

The 15-year-old student, Mohammed Ismail Hussain, was allegedly punished by the teachers, Mobina Begum and Wahid, on September 3. Hussain was reportedly asked to do as many as 100 sit-ups as punishment after being found quarreling with another student on the school premises of Royal Embassy High School at Madannapet area, police said, based on a complaint lodged by the boy's parents.

The boy's parents further alleged that it was only after being forced to do sit-ups by the two teachers that their son developed fever and died today while undergoing treatment.

Based on the complaint, the Madannapet police registered a case under Section 304-A for causing death by negligence, against the two teachers, an investigating officer told PTI.

After the post-mortem report of the boy is out, further action will be initiated, the police officer said, adding that the exact cause of the death, whether it had happened due to fever or after being subjected to corporal punishment was still not known.

The parents said that though Hussain developed fever on September 3 itself was immediately taken to a hospital, he had not informed them about the punishment until September 10.

When parents and relatives brought the matter to the notice of school authorities, they got the boy admitted in another hospital.

After the incident, some relatives of the deceased held protests in front of the school and later allegedly damaged furniture, even as police intervened and brought the situation under control.
